ICE-CREAM FREEZER.

Specification of Letters Patent.

Patented June 11, 1907.

To all whom it may concern:

Be it known that 1, WILLIAM M. MILBURN, a citizen of the United States, residing at Sherman, in the county of Grayson and State of Texas, have invented a new and useful Ice- Cream Freezer, of which the following is a specification.

My invention relates to ice cream freezers, and its ob'ectis to provide a device of this character aving a rotatable ice receptacle adapted to freeze cream as the same is applied to the outer surface of the rece tacle.

A still further object is to provi e means for removing the frozen cream and directing it into a receptacle rovided for it.

A still further 0 ject is to employ novel means for feeding cream to the rotatable receptacle and for preventing the same from overflowing into the receptacle containing the frozenmaterial.

With the above and other objects in view the invention consists of a rotatable cylinder in which ice, etc. is adapted-to be placed, and

this'cylinder has a normally closed outlet whereby the same can be readily cleaned subsequent to use. The cylinder is mounted above a tray to which the cream is adapted to be sup lied through a distributing trou h located a 'acent one end of the cover of t e freezer an cylinders are disposed upon the rotatable ice receptacle for the purpose of I holding the cream in proper position upon the ice receptacle during the freezing operation and to revent it from overflowing into the receptac e containing the frozen cream.

The invention-also consists of an adjustable knife which contacts with the outer surface of the ice rece tacle and serves to remove therefrom t e accumulated frozen cream and to direct it onto a chute which i 'serv s to convey it to a receptacle provided for t e frozen cream.

The invention also consists of certain other novel features of construction and combination of parts, the preferred form of which will be hereinafter more fully described and In the accompantyin shown the referred orm In said of the freezer, a portion of the cover bei removed. Fi 2 is a vertical longitudina the freezer. Fig. 3 is a secof my invention.

awings,-Figure l is a plan view 3 tion on the line 0ca; of Fig. 2. Fig. 4 is a detail view of the distributing trough detached and Fig. 5 is a similar view of the combine knife and chute.

Referring to the figures by numerals of reference, 1 is a casing of any suitable contour and proportions, the forward portion 2 thereof being reduced in size and closed by a hinged lid 3. A cover 4 is hinged to the opposite end of easing 1, and extends over the entire casing up to the upper edge of the lid 3 and is provided with suitable means 5 whereby it may be secured to said lid so as to close the entire casing. The end of the cover 4 adjacent its hinges is concaved, as shown at which extends a funnel 8 which is adapted to direct cream into a perforated distributing trough 9 which is supported beneath the openings 7 by means of straps 10 which depend from the cover. The trough is removable from these straps by sliding it longitudinally and can, therefore, be conveniently detached for the purpose of cleaning.

Bow springs 11 are disposed upon the bottom of the casing l and support a pan 12 havj ing a distributing cyllnder 13 arranged therein adjacent one end. This cylinder extends from one side to the other of the pan and lies close to a large freezing cylinder 14 i which extends into the pan 12. A tube 15 is located at one end of the cylinder 14 and constitutes a bearing therefor, said tube having a stem 16 therein provided with a head 17 which is held normally seated upon the inner end of the tube by means of a spring 18. Said head serves therefore to close the tube 1 and prevent the escape therethrough of any l of the contents of the cylinder 14. However, by pressing the stem inward this head 17 will be removed from the inner end of the 1 tube 15 and the contents'of the cylinder 14 j can therefore be readily drained therethrough. The other end of the cyhnder 14 has a large opening 19 surrounded by a threaded flange 5 20 which is adaptedto be engaged by a screw cap 21 having a stem 22 rojectlng from it and constitutmg the other caring of the cylinder 14. To this stem 22 is secured a disk 23 from which extends a grip or handle 24. 1 It will of course be understood that the disk 23 can be dispensed with and instead a crank l of the ordinary construction substituted 6, and has a series of openings 7 from one of rotation of cylinder 14.

Q erases therefor, and for the gri 24. However, when the disk 23 is utilize the same can be employed as a fly wheel for facilitating the It will of course be understood that both the tube 15 and the stem 22 are journaled within oppositesides of the casing 1, and the cylinder 14 is of such proportions as to fit between the sides of the pan 12 and to project downward into said pan and close to the adjusting cylinder 13.

A small guard cylinder 25 is rotatably mounted between arms 26 which are pivoted within casing 1 adj a'cent one end thereof and this cylinder is normally supported by gravity upon the cylinder 14 at a point above the distributing trough 9 and serves to prevent cream from flowing over the freezin cylinder during its rapid rotation and be ore the cream has had a chance to freeze.

Located within the casing 1 near the lid3 are spring arms 27 to which are secured the ends of a knife 28 which extends longitudinally of the cylinder 14 and contacts with the outer surface thereof. Thumb screws 29 extend from the ends of this knife through angular brackets 30 located upon the sides of the casing 1, and by manipulating these thumb screws the knife can be adjusted toward or away from the cylinder 14. A chute 31 extends from the knife 28 and converges toward its outlet. This chute is inclined and is adapted to discharge from its outlet any material which may be cut from the cylinder by the knife 28. The outlet of the chute is disposed above a receptacle 32 adapted to receive frozen cream. This rece tacle is readily removable byopening the lid 3 and lifting the receptacle 32 from the forward reduced portion 2 of the casing 1'. The cylinder 14 is provided upon its inner surface with lon itudinally-disposed cleats or blades 33 whic h are utilized for the purpose hereinafter setforth.

In using the freezer herein described, the c linder 1 1 is removed from the casing and the screw cap 21 is detached. A mixture of ice and salt is then placed within the cylinder and the cap is replaced. The cylinder is then reseated with its tube 15'and stem 22 in position upon the sides of the casing 1. The

cover 4 and lid 3 are then fastened in closed osition and cream is poured through the funnel 8 into the distributing trough 9. This trough will spread the cream over the cylin- 'ders 14 and 13 throughout their lengths and tated very rapidly, but by providing the guard cylinder any danger of this character is obviated.

When it is desired to clean the cylinder 14 the same is removed from the casing and placed with its tubular bearing downward. The stem 16 is then pressed inward so as to remove its head from the inner end of the tube, and therefore the liquid contents of the cylinder will flow downward through the stem and by pouring water into the other end of the cylinder the same can be thoroughly cleaned. The blades or. cleats 33 within the cylinder 14 are provided to cornpel the contents or" the cylinder to rotate therewith, thereby insuring a practically even tem erature of all portions of thesurfaces of t e cylinder and rendering said cylinder more easy to rotate.

The pan 12 is preferably provided upon its bottom with straps 3 1 which embrace the ends of springs 11 to prevent displacement of the pan. A shaft 35 having an angular extension 36 at one end is journaled u on the bottom of the casing l and beneath t at end ofd the an 12 in which cylinder 13 is mounte casing 1, and terminates in a lever 37 whereby the shaft can be manually operated to turn the extension 36, and positively raise the pan 12 and cylinder 13.

The pan 12 can be readily reached throu h the rear end of the casing which is norma y closed by a sliding door 38.

A freezer such as herein described can be constructed at comparativel slight cost and by reason of the fact that the cream is distributed over the freezing cylinder in a thin sheet the operation of freezing a quantity of cream is rendered very rapid and thorough.

Havin thus described the invention, what is claime is in a freezer the combination with a casing; of a yieldingly supported receptacle therein, manually operate means engaging the re= ceptacle for tilting the same, a distributing cy inder j ournaled within the receptacle, an ice containing cylinder rotatably mounted within the casing and projecting into said receptacle and against the distributing cylinder lrnife adjustably mounted adjacent,

an bearing upon, the ice containing cylinder be gradually con- Tiis shaft extends through one side of The cylinder 13 serves to distribute the ing cylinder at a oint between and above 5 for removin frozen material therefrom, a chute exten 'ng from and adjustable with said knife, a receptacle within the casing for receiving material from the chute, and a r0- 1 tatable guard seated by gravity upon and l extending longitudinally of the ice contain- 1 In testimony that I claim the foregoing as my own, I have hereto aflixed my signature to in the presence of two witnesses.
